[PATCH v11 11/12] drm/mediatek: dpi: Only enable dpi after the bridge is enabled

[Bo-Chen Chen <rex-bc.chen@mediatek.com>]

From: Guillaume Ranquet <granquet@baylibre.com>

Enabling the dpi too early causes glitches on screen.

Move the call to mtk_dpi_enable() at the end of the bridge_enable
callback to ensure everything is setup properly before enabling dpi.
